ONE Engine Moving Average Calculator (T1)
x402
ONE Engine Moving Average Calculator (T1) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).
Computes a moving average over a provided array of numeric values with configurable window size, scale, and normalization options.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the smoothed moving average series computed from the input array, reflecting the configured window size, optional normalization bounds (min/max), scale factor, offset, and decimal precision.
Example use cases
Smooth stock price series
“I have a list of daily closing prices for the past 30 days — can you run a moving average over them with a window of 5 days, rounded to 4 decimal places, so I can see the trend more clearly?”
Normalize sensor readings
“I'm getting noisy readings from a temperature sensor: [22.1, 23.4, 21.9, 24.0, 22.8, 23.5, 24.1]. Can you apply a 3-point moving average, scale the output to a 0–100 range with min 21 and max 25, and give me 2 decimal digits?”
Smooth agent-generated metric stream
“Here are 20 latency measurements from my API monitoring run: [45, 52, 48, 61, 55, 49, 53, 60, 58, 47, 50, 55, 62, 59, 48, 51, 57, 63, 60, 52]. Apply a 4-point moving average and return the smoothed values rounded to 1 decimal place.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/moving-average/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call moving average computation without provisioning any infrastructure. Ideal for AI agents that occasionally need to smooth numeric series (sensor data, prices, metrics) without bundling a math library. The $0.0005 per call price makes it cost-effective for low-to-medium frequency use. Prefer this over running local computation when the agent environment lacks numeric libraries or when you want a stateless, auditable computation step in an automated pipeline.
Side effects
- Missing required 'values' field returns a validation error
- Array exceeding 1000 elements may be rejected
- Non-finite numbers (NaN, Infinity) in the array cause computation errors
- Invalid window size (e.g. larger than array, non-integer) returns an error
- Insufficient USDC balance or failed x402 payment results in 402 Payment Required
- Malformed JSON body returns 400 Bad Request
